The Cosmological Dipole in Tilted Anisotropic Universes

Alicia Martín, Constantinos Skordis, Deaglan J. Bartlett +3

There is tentative evidence for a mismatch between the rest frames of matter and the cosmic microwave background, the "quasar dipole anomaly". We consider such a dipole in tilted a…

Khronon-Tensor theory reproducing MOND and the cosmological model

Luc Blanchet, Constantinos Skordis

We propose an alternative scalar-tensor theory based on the Khronon scalar field labeling a family of space-like three-dimensional hypersurfaces. This theory leads to modified Newt…

Stealth black holes in Aether Scalar Tensor theory

Constantinos Skordis, David M. J. Vokrouhlicky

The Aether Scalar Tensor (AeST) theory is an extension of general relativity(GR) successful at reproducing galactic rotational curves, gravitational lensing, linear large scale str…

Relativistic Khronon Theory in agreement with Modified Newtonian Dynamics and Large-Scale Cosmology

Luc Blanchet, Constantinos Skordis

We propose an extension of General Relativity (GR) based on a space-time foliation by three-dimensional space-like hypersurfaces labeled by the Khronon scalar field . We show th…

Towards galaxy cluster models in Aether-Scalar-Tensor theory: isothermal spheres and curiosities

Amel Durakovic, Constantinos Skordis

The Aether-Scalar-Tensor (AeST) theory is an extension of General Relativity (GR) which can support Modified Newtonian Dynamics (MOND) behaviour in its static weak-field limit, and…

Aether scalar tensor theory: Hamiltonian Formalism

Marianthi Bataki, Constantinos Skordis, Tom Zlosnik

The Aether Scalar Tensor (AeST) theory is an extension of General Relativity (GR), proposed for addressing galactic and cosmological observations without dark matter. By casting th…
